Questions & Step-by-Step Solutions
In a mixture of two liquids, if the first liquid is 25% alcohol and the second is 75% alcohol, what is the overall percentage of alcohol if equal volumes of both liquids are mixed?
Step 1: Identify the percentage of alcohol in the first liquid, which is 25%.
Step 2: Identify the percentage of alcohol in the second liquid, which is 75%.
Step 3: Since we are mixing equal volumes of both liquids, we can find the average percentage of alcohol.
Step 4: Add the percentages of alcohol from both liquids: 25% + 75% = 100%.
Step 5: Divide the total by 2 to find the average: 100% / 2 = 50%.
Step 6: The overall percentage of alcohol in the mixture is 50%.
